PROBLEM TO BE SOLVED: To provide an LED power supply device for actualizing a well-workable ground wiring construction for an outdoor luminaire using an LED as a light source.SOLUTION: The LED power supply device at one end of which an LED-arranged lamp fitting part is mounted, the other end of which is built in a pole part to be embedded in a ground, and to which an AC power supply is input to supply a DC current to the LED, includes a conductive case sealing an internal circuit, a first ground terminal provided inside the case, a power supply ground wire connected via the first ground terminal to the case and the internal circuit and pulled outside the case, and a second ground terminal provided on the outer face of the case so that a relay ground wire connected to the ground terminal of the lamp fitting part is connectable thereto. The power supply ground wire and the second ground terminal are electrically connected to each other via the case. |
